Scale Insect
A small, immobile insect that appears as a flat or domed, waxy bump firmly attached to a stem or leaf, easily mistaken for a plant blemish rather than a living creature.
true-bug
Javanese Leaf Insect
A broad, veined, leaf-green body makes this insect nearly indistinguishable from the foliage it feeds on, a masterclass in disguise native to the forests of Southeast Asia.
mantis-stick
Goliath Stick Insect
One of the largest stick insects in the world, this vivid green giant unfurls startling crimson underwings when startled, briefly abandoning its disguise as foliage.
mantis-stick
Walking Stick Insect
A master of disguise that has evolved to look almost exactly like a twig, bark or leaf, remaining motionless for hours to avoid the notice of hungry birds and lizards.
mantis-stick
Water Stick Insect
An extraordinarily twig-like aquatic predator that lies motionless among pond weed, grasping passing prey with spiny raptorial forelegs while breathing through a long tail-like snorkel.
true-bug
Leaf Insect
A living illusion, this flattened green insect reproduces the veins, edges, and even blemishes of a real leaf so precisely that it can vanish while resting in plain sight.
mantis-stick
Giant Prickly Stick Insect
A hefty, spine-covered phasmid that mimics dead leaves and curled bark, and when threatened, arches its abdomen like a scorpion's tail in a dramatic bluff display.
mantis-stick
Indian Stick Insect
A slender, twig-mimicking insect so unremarkable in stillness that it disappears among the stems it feeds on, one of the most widely raised stick insects in the world.
mantis-stick
Termite
A pale, soft-bodied social insect that lives in hidden colonies and feeds on cellulose in wood and plant debris, often mistaken for an ant despite belonging to an entirely different insect order.

Caddisfly
A moth-like insect whose larvae are famous for constructing portable protective cases out of silk and whatever sand, twigs, or debris they can find.
aquatic-insect
Earwig
A slender, reddish-brown insect easily identified by the pair of curved, forceps-like pincers at the tip of its abdomen, often found hiding under mulch, bark, or garden debris by day.

Vietnamese Walking Stick
A slender tropical stick insect popular in classrooms and terrariums, notable for females that can produce healthy offspring entirely on their own, without ever mating.
mantis-stick
Cochineal
A tiny, sedentary scale insect that lives clustered on prickly pear cacti beneath a protective coat of white, waxy fluff, historically prized for the deep red pigment it produces.
true-bug
Walking Stick
A remarkably twig-like insect with a long, slender, brown to green body and thin legs, so effective at mimicking a plant stem that it can be nearly invisible while motionless on vegetation.
mantis-stick
Giant Walking Stick
The longest insect in the United States, this brown, thread-thin giant sways gently on its perch to complete the illusion of a wind-stirred twig.
mantis-stick
Mealybug
A soft, oval insect coated in a powdery white waxy secretion that gives it a fuzzy, cotton-like appearance, typically found clustered in leaf joints and along stems of houseplants.
true-bug
Spittlebug
A small hopping true bug best known in its nymph stage, which surrounds itself in a frothy mass of white foam on plant stems, commonly called cuckoo spit.
true-bug
Flat-backed Millipede
A slow, armor-plated decomposer whose body segments flare into flat, wing-like keels, giving it a distinctly ribbed, tank-like silhouette compared to rounder millipedes.
myriapod
Grub Worm
A plump, C-shaped, creamy-white larva with a distinct brown head, living underground where it feeds on grass and plant roots before eventually maturing into a scarab beetle.
beetle
Daddy Longlegs
A small, oval-bodied arachnid carried on extremely long, thread-like legs, distinct from true spiders in having a one-piece fused body and no silk glands or web.
arachnid
Blister Beetle
An elongated, soft-bodied beetle with a distinctly narrow neck, often seen feeding in small groups on flowers, and known for releasing a defensive chemical from its leg joints when disturbed.
beetle
Bordered Plant Bug
A dark, oval-bodied true bug with a distinct pale margin around its wing edges, often mistaken for a large ant or beetle when its nymphs cluster together in tight groups.
true-bug
Common Wasp
A black-and-yellow social wasp with a distinct anchor-shaped mark on its face, common around gardens and picnics in late summer as its colony reaches peak size and workers seek out sugary food.
